The Krenitzin Islands are a small archipelago in the eastern Aleutian Islands of the U.S. state of Alaska. They lie east of Unalaska Island, off the western coast of the Alaska Peninsula, and are part of the larger Fox Islands group.
Geography
The islands consist of a series of low‑lying, volcanic islands and rocky islets. The most notable named islands within the group include Unalga Island, Umak Island, and additional smaller islets. The terrain is generally rugged, with cliffs, sea‑caves, and sparse tundra vegetation. The surrounding waters are part of the Bering Sea.
Naming
The archipelago is named after Russian explorer Pyotr Krenitsyn (also spelled Krenitzin), who participated in the 18th‑century Russian expeditions that charted parts of the Aleutian chain.
Human Presence
The islands are uninhabited; there are no permanent settlements or infrastructure. Historically, the Aleut (Unangan) people used parts of the Aleutians for seasonal hunting and fishing, but there is no documented permanent habitation on the Krenitzin Islands.
Conservation
All of the Krenitzin Islands are incorporated into the Alaska Maritime National Wildlife Refuge. In 1976, the United States designated the Krenitzin Islands Wilderness, providing the highest level of protection for the land and its wildlife under the Wilderness Act. The area supports seabird colonies, marine mammals, and serves as an important habitat for migratory birds.
Administration
The islands fall under the jurisdiction of the Aleutians West Census Area in the Unorganized Borough of Alaska. They are managed by the U.S. Fish and Wildlife Service as part of the refuge system.
